Genetic influence explains almost 60% of the variation in GCSE exam results, twin studies suggest.

Scientists studied academic performance in more than 11,000 identical and non-identical 16-year-old twins in the UK.

The team from King's College London found that on average, genes explained 58% of differences between GCSE scores in core subjects such as maths.

Differences in grades due to environment, such as schools and families, accounted for about 36%.

The remaining differences in GCSE scores in maths, English and science are explained by environmental factors unique to each person, say the researchers.

Seems like a massive oversimplification to me! 🙄
